scope:

This International Standard lays down test conditions and strength requirements to be met by: a) Case A (see Figure 1 a): Drawbar couplings and corresponding drawbar eyes for rigid drawbars which are provided for use on rigid drawbar trailers (see 3.2) with a maximum design total mass, C+S, exceeding 3,5 tonnes and: a vertical static load S (see 3.1) exceeding 10 % of their design total mass, and/or a vertical static load S greater than 1 000 kg and up to 2 000 kg. b) Case B (see Figure 1 b): Drawbar couplings and corresponding drawbar eyes for use on vehicle transport combinations, provided for a technical mass C exceeding 3,5 tonnes.
